Android Studio 3.0 with Flutter & Dart plugin not recognizing USB or virtual devices when clicking Play

Steps to Reproduce

Run "Flutter Devices" in Windows 10 Command Prompt shows that a device is connected.

flutter devices
1 connected device:
SM N950U1 • ce06xxxxxxxx • android-arm • Android 7.1.1 (API 25)

However, pressing Run in Android Studio 3.x returns this error popup:

No connected devices found; please connect a device, or see flutter.io/setup for getting started instructions.

https://flutter.io/setup/ guides the user to this link https://flutter.io/setup-windows/#android-setup

And that page has no directions on how to setup the IDE to recognize that you have a device attached or to have it work with the virtual device.

The same error window pops up when you select a virtual device and press Play in Android Studio. However, pressing Play on an Android project works fine with virtual and USB devices.

Logs

Run your application with flutter run and attach all the log output.
Run flutter analyze and attach any output of that command also.

N/A. The command line tool works fine. The Android Studio plugin has issues.

Just curious, have you configured the Flutter plugin in IntelliJ under the Languages & Frameworks section? If this configuration does not have the right Flutter installation path, the Flutter plugin will not be able to launch the app via Android Studio.

Same problem here. Same config as OP. Happens in both AS and IntelliJ IDEA CE.

[mit-mit]

The Flutter IDE plugin is expected to show the exact same list of devices as flutter devices does. If they don't, then that a bug. I'm going to port this bug over to the intellij specific tracker.

[mit-mit]

@pawelkw, just checking are you also on Windows? And also seeing the expected list of devices in flutter devices ?

[pawelkw]

@mit-mit No, I'm on a Mac with High Sierra,
Yes, all expected devices show up correctly in CLI using flutter devices.

[mit-mit]

@pawelkw, @tomnta, would you both mind trying to update to the 19.1 version of the plugin and see if the issue still repros there?

[tomnta]

@mit-mit You bet.. ok, updated to version 19.1 but it still doesn't work for me in Android Studio 3.0.1.

F:\Android-Workspace>flutter create my_app
Creating project my_app...
Wrote 64 files.

Running "flutter packages get" in my_app...           9.7s

[√] Flutter is fully installed. (on Microsoft Windows [Version 10.0.14393], locale en-US, channel alpha)
[√] Android toolchain - develop for Android devices is fully installed. (Android SDK 27.0.1)
[√] Android Studio is fully installed. (version 3.0)
[√] IntelliJ IDEA Community Edition is fully installed. (version 2017.2)
[√] Connected devices is fully installed.

All done! In order to run your application, type:

  $ cd my_app
  $ flutter run

Your main program file is lib/main.dart in the my_app directory.

Thanks for confirming!

Working for me now. Pulled repo + 19.1 plugin. Created new project in IntelliJ IDEA CE - devices show up correctly now. Project is deployed to selected device correctly. Mac High Sierra.
